My 87 is still overheating at idle, need advice, I’ve replaced my thermostat to a new 195 with jiggle pin, new water pump heavy duty, new csf rad, and I also changed my clutch fan a couple months ago I let the truck idle for 20 minutes or so and it stayed around 210 until I checked it at around the30 minute mark and it was pushing close to the red. Any advice?
